ABB SU202M-K2 Safety Relay Module 24VDC Input

ABB SU202M-K2 is a two-pole miniature circuit breaker from ABB's System Pro M Compact family, providing overcurrent protection for dual-line circuits. It features a K-curve trip characteristic and a nominal current rating of 2 A, with a short-circuit breaking capacity of up to 10 kA (UL489). This 2P device interrupts both conductors of the circuit simultaneously, making it suitable for protective applications in small control and distribution circuits within industrial or commercial panels. The SU202M-K2 is UL489-listed, ensuring compliance with standard safety requirements for circuit protection devices in North America. Designed for modular panel installations, it integrates with ABB's System Pro M Compact ecosystem and can be used wherever compact, dependable two-pole protection is needed. Typical applications include protection of control feeders, logic circuits, and other low-current branch circuits where precise, reliable isolation is required.
